Embodiment 1

[0098] Such as figure 1 As shown, the embodiment of the present invention provides a method for controlling an avatar, including:

[0099]Step 101: Obtain the first human face image corresponding to the user by photographing the user's face, identify the outline of the first human face image, and identify the key points included in the outline of the first human face image;

[0100] Step 102: According to the position of the key point included in the outline of the second human face image stored in advance and the position of the key point included in the outline of the first human face image, calculate the key point included in the outline of the first human face image relative to the preset The displacement of the key point that the profile of the second people's face image that stores comprises, and the second people's face image is the people's face image that obtains before;

[0101] Step 103: Control the user's avatar according to the displacement of the key points incl...

Embodiment 2

[0104] An embodiment of the present invention provides a method for controlling an avatar. Wherein, the camera is used to continuously shoot the user's face to obtain a facial image corresponding to the user, and the virtual image corresponding to the user is controlled through the method of this embodiment according to the facial image corresponding to the user. see figure 2 , the method includes:

[0105] Step 201: photographing the user's face to obtain a facial image, and obtaining the first human face image corresponding to the user and the size and position of the first human face image from the facial image;

[0106] Specifically, the camera is used to capture the user's face to obtain the corresponding facial image of the user, and the first facial image is scanned through the existing facial image recognition algorithm to identify the first facial image in the first facial image And the size and position of the first face image.

[0107] Wherein, the first human f...

Embodiment 3

[0135] An embodiment of the present invention provides a method for controlling an avatar. Wherein, the camera is used to continuously shoot the user's face to obtain a facial image corresponding to the user, and the virtual image corresponding to the user is controlled through the method of this embodiment according to the facial image corresponding to the user. see Figure 5 , the method includes:

[0136] Steps 301-303: are respectively the same as steps 201-203 of Embodiment 2, and will not be described in detail here;

[0137] Step 304: Calculate the displacement of the contour of the first human face image according to the displacement of the key points included in the contour of the first human face image relative to the key points included in the contour of the second human face image;

[0138] Specifically, calculate the average displacement of the key points included in the outline of the first human face image relative to the displacement of the key points include...

Abstract

The invention discloses a method and device for controlling a virtual image and belongs to the field of computers. The method includes the steps that a first facial image corresponding to a user is obtained through shooting the face of the user, the contour of the first facial image is identified, and key points included by the contour of the first facial image are marked; according to positions of key points included by the contour of a second facial image stored in advance and positions of key points included by the contour of the first facial image, displacement, relative to the key points included by the contour of the second facial image stored in advance, of the key points included by the contour of the first facial image is calculated; according to the displacement, relative to the key points included by the contour of the second facial image stored in advance, of the key points included by the contour of the first facial image, the virtual image of the user is controlled. The device comprises an identifying module, a calculating module and a control module. Instantaneity and operation convenience of the virtual image can be improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for controlling virtual images. Background technique [0002] In online virtual communities, users often create an avatar for other users to recognize and recognize. Users can control the avatar to show their expressions to other users. Show yourself laughing. [0003] Assuming that the user needs to control the avatar to show a facial animation of laughing, currently the user can control the avatar in the following three ways, including: first, the user can control the avatar to show the facial animation of laughing through the shortcut key corresponding to the big smile Second, the user can control the avatar to present a laughing facial animation by inputting keywords such as "haha"; third, the user can control the avatar to present a laughing facial animation by clicking on the face of the avatar with a mouse. [0004] In the process of realizing the present inv...
